Abstract

UN COMPUESTO ORGANOMETALICO DE CROMO EN FASE GASEOSA SE PONE EN CONTACTO CON UN SUBSTRATO CONSTITUIDO POR LA SUPERFICIE INTERIOR DE LA VAINA TUBULAR (15) DE ALEACION DE ZR DEL ELEMENTO COMBUSTIBLE O LA SUPERFICIE EXTERIOR DE LAS PASTILLAS DEL MATERIAL COMBUSTIBLE; EL SUBSTRATO SE MANTIENE A UNA TEMPERATURA ENTRE 300 Y 600 (GRADOS) C. EL COMPUESTO ORGANOMETALICO PUEDE ESTAR CONSTITUIDO POR EL ACETILACETONATO DE CROMO. EL PROCEDIMIENTO PERMITE OBTENER UN REVESTIMIENTO DE OXIDO DE CROMO EN EL INTERIOR DE LA VAINA TUBULAR (5) Y/O SOBRE LA SUPERFICIE EXTERIOR DE PASTILLAS DE COMBUSTIBLE NUCLEAR. SE EVITA O SE LIMITA ASI LA INTERACCION PASTILLAS-VAINA DURANTE LA UTILIZACION DE ESTE ELEMENTO COMBUSTIBLE EN EL REACTOR.A GAS PHASE CHROME ORGANOMETALLIC COMPOUND IS IN CONTACT WITH A SUBSTRATE CONSTITUTED BY THE INNER SURFACE OF THE TUBULAR CASE (15) OF ZR ALLOY OF THE FUEL ELEMENT OR THE OUTER SURFACE OF THE FUEL MATERIAL PADS; THE SUBSTRATE MAINTAINS A TEMPERATURE BETWEEN 300 AND 600 (DEGREES) C. THE ORGANOMETALLIC COMPOUND MAY BE CONSTITUTED BY CHROME ACETYLACETONATE. THE PROCEDURE ALLOWS TO OBTAIN A CHROME OXIDE COATING INSIDE THE TUBULAR CASE (5) AND / OR ON THE EXTERNAL SURFACE OF NUCLEAR FUEL PADS. THE INTERACTION OF THE PADS-SHEATH IS DUE TO OR AVOIDED DURING THE USE OF THIS COMBUSTIBLE ELEMENT IN THE REACTOR.
